Application of electric control system in power plant

Abstract

Abstract: The electric control system manufactured by Beijing Sifang Relay Protection Automation Corporation Limited is adopted in Shanxi Yuncheng Power Generation Corporation Limited of Datang International Power Generation Corporation Limited. The usage of the electric control system for protection, measurement and control was introduced. In this system, the communication with measurement and control equipment is all realized by LONWRORS or RS485 field bus, a great amount of control cables were saved, the construction cost was reduced, and the automation level was raised. Aiming at the characteristics of electric control system, the network structure, system scheme, system maintenance and others were summarized.

Key words: electric control system, distributed control system, measurement and control, field bus, communication management unit, network
